I think this thread is a fantastic idea. Lately this forum has been flooded with people looking for other Texas cosplayers. Should cut down on excess threads.

The Texas Metroplex Cosplay Coalition is an extremely active group here in DFW, any one 16+ is welcome to join. But be sure to follow the instructions found on the forums when you sign up!

Sadly, I don't think The Chika Chika Ninja's are active, although Shinobi_Misa, the cosplayer that started that thread is part of another successful J-Pop/ cosplay dance group. I think its Texas based, but you'd have to ask her for confirmation.
